Abstract
A system and method for switching power sources for an aircraft electric brake system is disclosed. The method removes battery power from electric brake actuator controls during flight until landing gear extension occurs. The method utilizes a logic circuit to switch between available power sources based on a plurality of control signals. The method minimizes the total power drawn during flight, and saves battery power if the aircraft calls for operating on battery power only.
Claims16
A system for switching power for an electric brake system, the system comprising:
- a brake system control unit configured to generate at least one power control signal, wherein the at least one battery control signal is configured to switch a power off from an electric brake system during flight;
- and
- at least one electric brake actuator control coupled to and controlled by the brake system control unit, the brake system control unit being configured to control switching of the battery power for the at least one electric brake actuator control in response to the at least one power control signal.
A system for switching power for an aircraft electric brake system, the system comprising:
- at least one electric brake power supply unit coupled to at least one electric brake actuator control and to a brake system control unit, wherein the at least one electric brake power supply unit is configured to supply power to the brake system control unit and to the at least one electric brake actuator control;
- and
- at least one power switching logic circuit coupled to the at least one electric brake power supply unit, wherein the at least one power switching logic circuit is configured to switch power sources for the brake system control unit and for the at least one electric brake actuator control.
A method for switching power for an electric brake system, the method comprising:
- receiving a plurality of control signals from the aircraft electric brake system;
- and
- switching power sources for the aircraft electric brake system in response to the control signals.
